These covid posts on hn are some of the most hostile threads I've seen on the internet. Between the intense emotions, conspiracy theories where people thinks they're constantly under attack, and various frustrations. Just don't take it personal. Or honestly dont bother with covid threads on this site. I'd treat them as read only and get your info elsewhere

I'm not sure that modern democracies exist for sufficiently long to make strong claims about their stability, and premodern democracies weren't particularly stable (as far as I know, I'm not too good at history).

No one is forcing to use you WhatsApp or the others. You have free will. These apps come and go and you can even come up with your own app and make others use it. Free market for you my friend.
Yeah, that's me :)
Yes, there are. About 6k per car. But this just preempts the price development in a growing market. And it helps the market to grow to a point where the cars do get cheaper because of scaling.
On the other side: fossil fuels and especially car combustion engines are not taxed along the negative impact they have by toxic and carbon emissions.

Not exactly CSS's fault but I'm definitely in the "img should be a block" camp. It's what people expect almost all of the time and would prevent people new to web design from diagnosing the small gap left underneath despite removing margins.
While TMSC is no doubt ahead of competition, it is just by margin of 1-2 generations at max, which accounts for max 2-3 years for friendly country like Korea to catch up. So if some Taiwan politics comes into play, we will just lose the progress for some years of semiconductor fab tech, not a small thing but it is not that the chips couldn't be built if not for Taiwan. We would just lose something like 10-20% of performance in the chip.

That sounds pretty desperate. Is there a precedent for companies communicating like this in India?
Constructivism is a less extreme position than finitism. It's hard to describe it, but it's got something to do with not believing that a mathematical object exists until it's been "constructed". I'm not sure if it can adequately be described without referring to formal logic. One motivation for considering this philosophy is that mathematics becomes more "computable" when you do, but there are other reasons as well.

The statement that there are infinitely many integers is true in constructive mathematics: Given any integer, you can construct some integer larger than it. Likewise, the statement that the real numbers are uncountable is also true: Given any sequence of real number, it's possible to construct a real number that's not in the sequence (using Cantor's method).

The claim that all real numbers are computable doesn't have any constructive content, so its truth depends on which version of constructivism you believe in. Personally, having looked into this, I prefer versions of constructivism in which the claim is false, because then you can claim things like every continuous function on R is locally uniformly continuous (which weirdly enough, implies that not all real numbers are computable, without asserting the stronger claim that an uncomputable one exists).
These used to be more common in the US and some still exist but the big telcos have all stopped upgrading their equipment which deliberately chokes the available bandwidth at those locations. They also deliberately don't on-board any new ones. This is the same strategy they used against Netflix if you recall - deliberately don't upgrade the linecards at choke points to ensure Netflix packets get dropped. Netflix eventually caved (and raised prices) so we're all paying for it on both ends: as ISP customers and Netflix subscribers. Who doesn't like a bit of double-dipping?

They really really want to go back to the long-distance telephone days where people paid according to some kind of metering plan. That's the whole push behind getting rid of Net Neutrality (which is how the internet always worked up to that point - so much so we had to invent a new term to describe what was taken away). Why invest in new plant, fiber, or equipment? Just stop upgrading or upgrade very slowly and let increases in data usage dump money directly into your pocket. A great gig if you can get it.
The last two paragraphs make me very happy.

I am tired of most (non-tech) mainstream news outlets blindly regurgitating Telegram's "encryption" claims, or mentioning Telegram in the same clause as Signal under the umbrella of "more secure alteratives".
I've kept pointing out for years that e-mail can be used for this. You can decompose e.g. even something like Twitter into mail servers + forwarding + mailing-lists. Back in 2001 I was part of using Qmail as a distributed message broker. We built a domain name registry with live updates where messages between backend components were sent as e-mails. It worked very well, and you get the ability to federate for free.
I think its the duality between macro and micro.

In strategy games, you're often concerned with the macro game. Yes there's "micro" in strategy games, but you can't ever take control of a single pawn and play as them (I think the one game that tried to do this was Dungeon Keeper 2, where you could "possess" a minion and play a limited fps-style game in your dungeon).

FPS gives you a quick, short term escape from reality as you're transformed into a different, perhaps more controlled reality with very well defined and measurable objectives.

Strategy and open world games like Factorio, Stardew Valley, Minecraft etc. let you go nuts, with no real objectives except those that you make yourself.

I'm guessing human brains like variety. So if you have to strategize too much at work, you're likely to want a mindless romp through zombies with a machine gun. If you're doing mindless enterprise coding, maybe you're likely to want to plan, build and optimize a gigafactory in factorio to feel more in control of your world.
True, but timing is everything. 2021 still seems to early for mass EV adoption, 2022 might see a proper ramp up and we will have to wait until 2025 or so, for better battery tech and cheaper batteries, to have EVs truly on an equal footing to internal combustion engine cars.

After that things will probably pick up and we'll get the hockey stick that leads to what you're saying.

If you got a lot of money you should give back to what propelled you there. You may call it investing with a loss but that'd be just the right thing to do. Everything is not about the money, making money and more money.
"Thus humans do not invent mathematics, but rather discover it, and any other intelligent beings in the universe would presumably do the same."

I pretty sure it's true also for other areas, e.g. engineering. I believe that first vehicles created by some alien civilization would work on a similar principles as ours.

The upside and downside of hybrid cars boils down to the same thing: Having two energy systems on-board. While often great, it also makes the whole system quite a bit more complex.

You need a gas tank and a battery, electric motors and internal combustion engines, and so on. I don't know how hybrid cars compare in terms of purchase price and maintenance costs, but on paper they are a much more complicated system.
>If the jobs in SF don't pay enough for people to live there, then definitely demand more pay, don't take the jobs or leave. The area is nice, but not that nice.

Oh man, how can you be so naive to not know. 50 houses + 51 residents means prices rise until of them leaves. There is no amount of money you can pay to solve this if you don't build enough housing.

WOW 1 paragraph of data > 48 page pdf of "look at me i did this first so i know what im doing" . Honestly this is quite dumb , waymo will NEVER i REPEAT NEVER make it to market let alone with any amount of volume ... And it has nothing to autonomy or tech ... just by virtue of having bulky expensive sensor's (which need to be serviced regularly) and power draw of the compute and tech .... other than having a very niche proof of concept like project loon i think waymo will also fold like all of its fellow google x brother-in.

Mainly more points of failure, and additional weight to my knowledge.

The electric motor allows superior city driving due to the nice fact that you have regenerative breaking and much more efficient low speed operation where an ICE would not be able to run at its most efficient RPMs. While the gas engine gives a lot of convivence that you might otherwise lose.

The downside is now you have two drivetrains that need to integrate into a very limited space, with limited weight as the whole goal was to make an more efficient car. Its also non-trivial to make a good transmission let alone one that has two inputs, or even an integrated electric motor.

Batteries in a hybrid are also pushed much harder in a way. Batteries are often rated over 20hr discharge cycles as you can generally get more power out of a battery by discharging it slowly. Asking 1A from a 100Ahr battery vs 1A from a 1A battery is very different in terms of effective capacity as well as the longevity of the cell. Given that batteries are so heavy and you need two drivetrains you can only add so much battery capacity. The end result is that its easy for the batteries to age faster in a hybrid.

A surmountable issue is heat, batteries don't play well outside a range of limited range of temperatures. Too cold and they will have less effective capacity, too hot and they can be damaged or degrade faster. This issue can be overcome, but is just another way there is more complexity than Tesla's 'the floor is a battery approach'.

Hybrids are cool, but they are hard to make right is the tldr.
I find this approach fascinating, it's simple yet so intuitive! I hope you keep going.
>Yet, the Bob from software can write a sloppy spec and Alice from hardware can not care about the spec being sloppy.

Yellen’s comments really don’t justify the headline. Said differently, the headline should be something like “Janet Yellen Will Consider Ways to Limit the Use of Cryptocurrency for Illegal Transactions”. I.e. stuff for which it’s already illegal to transact in dollars. At this point, she’s not coming for your Bitcoins, though unfortunately I think framing crypto as directly adjacent (or an enabling mechanism) to illicit activity is a step in that direction. But honestly this has been a criticism leveled at Bitcoin for years and nothing has changed.

> Whenever you see “loss”, substitute with “penalty” and things will become much clearer.

Penalty already has a meaning in machine learning so this substitution just adds more confusion instead clarifying things. Loss seems descriptive enough to me.
Sri Lankan here (that island under India). You would assume that this would go right over our heads, but a lot of people here are concerned and when I finally installed Signal, I noticed many people already there. Some of them, I never expected to see outside of WhatsApp or Viber.
Yes, I had hope in the early 2000's with XMPP, but considering 20 years later we still have a fragmented ecosystem and none of the actors are willing to push for a federated network (even the open source, NPO, Signal!) is really depressing.
There are a few standard definitions used in analytic philosophy: https://plato.stanford.edu/entries/realism/
Adapting your example to a component of a real project I'm working on:

JsonParser<Customer> customerP
= productP
. field("customer", productP
. field("name", stringP),
. field("address", productP
. field("street", stringP)
. field("zipCode", stringP)
. field("town", stringP)
. map(uncurry3(street -> zipCode -> town ->
new Address(street, zipCode, town))))
. map(uncurry2(name -> address ->
new Customer(name, address))));

This is a parser, not a serializer, but hopefully it's clear how this approach can be applied in the other direction. (I still have the analogous code on a branch somewhere, but the parsing logic needed a cleanup more, and sooner.)

Some of the uncurried function stuff can be cleaned up with dedicated wrappers for `BiFunction` and whatnot. And of course, the address parser could be extracted out if we want to unit test it separately.

I don't find the code I give above to be any worse than the code you gave (for that matter, I don't have the same "yuck" reaction to the C# example, either). I much prefer not needing extra data types that only serve to configure analogous translation code.

We can keep going back and forth, addressing the concerns we have about each other's approach, but it ultimately comes down to preference.
It's impossible to say without knowing actual prices and doing the math. If a profit can be made, most likely someone will do it.
From other technologies such as speech recognition, "how it works" seems to be - collect a lot of data and develop and train better and better models.

So tesla is collecting data, lots of it.

Additionally, there's the capitalism side of things - make sure you have a revenue stream to continue "develop and train"

So tesla has a revenue stream matched with the data collection.

So... Tesla is head and shoulders above Waymo in this.
I will need to verify each disc. I may not have to rip all of them, but I will probably do some sort of rapid de-duplication check. It will probably be much more involved than the normal toc disc id though. I might compare bits from random areas of each disc to verify it is the correct pressing. I'm still not 100% sure how I'll do it, but I don't want to store more than I have to.

I'd like to be able to take the pieces of a broken disc and verify somehow that it's a legit copy. Then I'd treat the pieces like every other copy of that disc and give the owner access.

Stubborn minority in this case would be the stubborn Signal users refusing to use Whatapp?

3 groups:

1. Uses Signal only

2. Uses both

3. Uses Whatsapp only

1 is the stubborn minority, 2 is slowly increasing, and 3 probably doesn't care enough to be considered stubborn, and definitely not minority.

At least that was my thought, this whole debacle reminded me immediately of the stubborn minority, so I'm very curious to see how it plays out.

Being a homeowner does not mean you live in single family house. Yes, I own my home in Oslo but I live in an apartment. We have shared garage areas which is indeed common in Norway even for people with single family homes. Garages are often clustered in Norway to keep neighborhoods car free.

We also have problems all across Norway with electrical capacity not being enough to install chargers in these garages. So upgrades to the grid has been necessary lots of places.

We only recently got a grid upgrade in my apartment complex to allow installation of chargers.
Only in short term. A single autocrat can be efficient and purpose-driven and can move mountains, but the next one has decent chances to be just a useless bloke, and the system doesn't have a feedback loop from citizens to correct the course via elections. So eventually all autocracies deteriorate.

Putin's autocracy deterioration has happened even during his lifetime.
That doesn't sound like the network effect, but rather granting a single person veto right over the privacy preference of the others. Just create the Signal group between the 4 of you and the network effect will ensure that democracy prevails

While I'm not a big Tesla fan, I don't think legislation is any indication of the actual safety that can be provided. Europe legislation tightly follows what German carmakers can deliver. Once they can offer the same features, it will be legal in no time.
I do not define anything, just use the US legal definition. Please see my other comment for the gov link and relevant quote.

We do not have in France any such legal construct (this is even forbidden by law).
You're being a bit pedantic here. Every time you engage autopilot, it literally tells you (in bold letters) to "Always Keep Your Hands on the Wheel" and to "Be Prepared to Take Over at Any Time". Keep abusing it and it will actually disable it for the rest of the drive. Did you know that?

There's no "impression" being given. Like I mentioned. There will always be a small fraction of irresponsible humans that will do dumb things. No amount of engineering can fix that.

Case in point is this video: https://youtu.be/VS5zQKXHdpM?t=88 Her mom is even helping this kid film this stupid act just for clout and views.

Tesla owners grilled him and said what he's doing is dangerous and irresponsible. He then deleted them all and turned off commenting. But people like to demonize Tesla owners. Which I find bizarre.
SVG screenshots are documented here: https://www.checkbot.io/article/web-page-screenshots-with-sv...

The main trick is to view your web app in a browser, print to PDF and then use Inkscape to auto convert from PDF -> SVG (with some caveats). Worst case you could recreate the screenshot from scratch in a vector editor.

The SVG icons are licensed from https://icons8.com/ (recommended!).
This exactly. The recommendations are, at best, a win win for you and some 3rd party that paid to be part of the win (but sometimes tries very hard to not make it seem so). It can be different, but only for the tech-savy (open source) and rich people (pay the tech-savy).
Oh please, your behavior will depend on what's socially acceptable at the time and you know it.
Is this the correct tool if you are trying to use a cheap tablet as a wireless display for a raspberry pi?

Edit: I don't think this would be a good solution. It mentions getting a qr code from the host machine and approving the connection inside the application. These things would be really hard to do on a pi with no screen over an ssh connection.
Isn't Hetzner heavy blocked by the large mail providers? I had similar issues with Digital Ocean, AWS, Linode etc when trying to self host. Even tried smarthosting via SES and that still made my very small volume of emails land in spam folders.
The slides:
https://pgm.di.unipi.it/slides-pgm-index-vldb.pdf

It seems they are only talking about compressing the index (keys) not the values.

Also, the slides seem to imply the keys need to be set in sorted order? That way their memory locations will be in increasing order too. That’s quite an important limitation, that means the index is read-only in practice once populated. Though it may still be useful in some cases.

Did I misunderstand?
I need to write it up but the SVG screenshot is documented on https://www.checkbot.io/article/web-page-screenshots-with-sv... and I'm using all the tricks from https://www.checkbot.io/guide/speed/ that the Chrome extension checks for.

The big wins are: don't require JS for any content in the page header, use minimal CSS + inline it, strongly prefer SVG images over bitmaps + inline them, use "font-display: swap" + go easy with how many fonts you need.

I also believe that a country like China take a lot of different considerations in to this equation such as people health. Not because of empathic care, but rather workforce and long term cost management.

They do things like this:

https://www.washingtonpost.com/science/2018/09/04/china-blam...

If they have a goal or idea they can paint with a really large brush and hit a few birds with a really big stone. It's both a strength and ofc a weakness.

Over here where actual market matters more we will often act much slower, which is a strength and a weakness. =)
Modern EVs can have bidirectional charging so they can charge each other. Hence if you run out and the grid is down you may be able to buy electricity off somebody else’s car. Don’t see this flexibility with gasoline.
That safety 'Report' from Waymo isn't a report at all though. It is a general overview on their approach how they say they will handle it and a direction. Basically a primer for regulators and customers that don't know anything yet about it. It is extremely light on numbers over time.
Besides all the other reasons already mentioned, its security model is somewhat dated. For example, it does not use forward secrecy, neither for chats nor for 1:1 calls. (Group calls do have forward secrecy.)

That said, I still use it over Signal when I can – cross-device messaging is very hard, UX wise (which device receives the notification, does "mark as read" properly sync across device, how is the behavior of a device coming back online after a while etc.), and Apple has almost perfected it at this point.
Thanks, that made my day. :)
Well I could do so, but as said the majority won't really see the benefits of pushing so hard. They're willing to switch but not willing to advocate.
Beyond "more efficient to move stuff around" by whatever definition of effincy, what would those principles be?
